RISEffectiveness of Impressed Current Technique to Simulate Corrosion of Steel Reinforcement in Concrete
Publisher: American Society of Civil Engineers
Abstract: Accelerated corrosion by means of the impressed current technique is widely used in concrete durability tests. In this study, the influence of varying the impressed current density level between 100 and 500 μA/
Structural Retrofitting of Deteriorated Concrete Lighting Poles Using FRP Sheets in Wet Layup—Field Application
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the structural retrofit of deteriorated reinforced concrete lighting poles using wet layup of fiber reinforced polymer (FRP) sheets. The study comprised of four full-scale Class B damaged poles and ...
Mechanism of Bond Behavior of Concrete Beams Strengthened with Near-Surface-Mounted CFRP Rods
Publisher: American Society of Civil Engineers
Abstract: Bond tests were conducted on concrete beams strengthened with near-surface-mounted (NSM) nonprestressed and prestressed carbon fiber-reinforced polymer (CFRP) rods under static loading. In the NSM technique, the CFRP rods ...
Experimental Investigation of Bond Fatigue Behavior of Concrete Beams Strengthened with NSM Prestressed CFRP Rods
Publisher: American Society of Civil Engineers
Abstract: Bond tests were conducted on 10 concrete beams strengthened with near-surface mounted (NSM) prestressed carbon fiber reinforced polymer (CFRP) rods under different fatigue load levels. In the NSM technique, grooves are cut ...
Mechanics of Bond Fatigue Behavior of Concrete Beams Strengthened with NSM CFRP Rods
Publisher: American Society of Civil Engineers
Abstract: Bond tests were conducted on 28 concrete beams strengthened with near-surface mounted (NSM) carbon-fiber-reinforced polymer (CFRP) rods under different fatigue load levels. In the NSM technique, the CFRP rods are placed ...
Bond Strength of Tension Lap Splices in High-Strength Concrete Beams Strengthened with Glass Fiber Reinforced Polymer Wraps
Publisher: American Society of Civil Engineers
Abstract: This paper presents the experimental results of the first phase of a study undertaken at the American University of Beirut to examine the effectiveness of fiber reinforced polymer (FRP) wraps to confine steel reinforcement ...
CFRP Strengthening for Punching Shear of Interior Slab–Column Connections
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental investigation studying the effect of retrofitting interior slab–column connections against punching shear failure with externally bonded carbon fiber reinforced polymer ...
Analysis of the Flexural Behavior of Partially Bonded FRP Strengthened Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: An investigation was conducted on the flexural behavior of partially bonded fiber-reinforced polymer (FRP) strengthened concrete beams focusing on the improvement of ductility. An analytical model was developed based on ...
Effect of Partial Unbonding on Prestressed Near-Surface-Mounted CFRP-Strengthened Concrete T-Beams
Publisher: American Society of Civil Engineers
Abstract: The flexural behavior of RC T-beams strengthened with prestressed near-surface-mounted (NSM) carbon fiber-reinforced-polymer (CFRP) reinforcement was investigated. The specific objective was to study the effect of partial ...
Polypropylene FRC Bridge Deck Slabs Transversely Prestressed with CFRP Tendons
Publisher: American Society of Civil Engineers
Abstract: Compressive membrane action in bridge deck slabs has been shown to considerably increase the failure loads of such slabs. Thus, the reinforcing requirement can be reduced if a system is configured to ensure development of ...
